NAME
HTTP::Config - Configuration for request and response objects
SYNOPSIS
use HTTP::Config;
my $c = HTTP::Config->new;
$c->add(m_domain => ".example.com", m_scheme => "http", verbose => 1);
use HTTP::Request;
my $request = HTTP::Request->new(GET => "http://www.example.com");
if (my @m = $c->matching($request)) {
print "Yadayada
" if $m[0]->{verbose};
}
DESCRIPTION
An "HTTP::Config" object is a list of entries that can be matched against request or request/response pairs. Its purpose is to hold
configuration data that can be looked up given a request or response object.
Each configuration entry is a hash. Some keys specify matching to occur against attributes of request/response objects. Other keys can be
used to hold user data.
The following methods are provided:
$conf = HTTP::Config->new
Constructs a new empty "HTTP::Config" object and returns it.
$conf->entries
Returns the list of entries in the configuration object. In scalar context returns the number of entries.
$conf->empty
Return true if there are no entries in the configuration object. This is just a shorthand for "not $conf->entries".
$conf->add( %matchspec, %other )
$conf->add( \%entry )
Adds a new entry to the configuration. You can either pass separate key/value pairs or a hash reference.
$conf->remove( %spec )
Removes (and returns) the entries that have matches for all the key/value pairs in %spec. If %spec is empty this will match all
entries; so it will empty the configuation object.
$conf->matching( $uri, $request, $response )
$conf->matching( $uri )
$conf->matching( $request )
$conf->matching( $response )
Returns the entries that match the given $uri, $request and $response triplet.
If called with a single $request object then the $uri is obtained by calling its 'uri_canonical' method. If called with a single
$response object, then the request object is obtained by calling its 'request' method; and then the $uri is obtained as if a single
$request was provided.
The entries are returned with the most specific matches first. In scalar context returns the most specific match or "undef" in none
match.
$conf->add_item( $item, %matchspec )
$conf->remove_items( %spec )
$conf->matching_items( $uri, $request, $response )
Wrappers that hides the entries themselves.
Matching
The following keys on a configuration entry specify matching. For all of these you can provide an array of values instead of a single
value. The entry matches if at least one of the values in the array matches.
Entries that require match against a response object attribute will never match unless a response object was provided.
m_scheme => $scheme
Matches if the URI uses the specified scheme; e.g. "http".
m_secure => $bool
If $bool is TRUE; matches if the URI uses a secure scheme. If $bool is FALSE; matches if the URI does not use a secure scheme. An
example of a secure scheme is "https".
m_host_port => "$hostname:$port"
Matches if the URI's host_port method return the specified value.
m_host => $hostname
Matches if the URI's host method returns the specified value.
m_port => $port
Matches if the URI's port method returns the specified value.
m_domain => ".$domain"
Matches if the URI's host method return a value that within the given domain. The hostname "www.example.com" will for instance match
the domain ".com".
m_path => $path
Matches if the URI's path method returns the specified value.
m_path_prefix => $path
Matches if the URI's path is the specified path or has the specified path as prefix.
m_path_match => $Regexp
Matches if the regular expression matches the URI's path. Eg. qr/.html$/.
m_method => $method
Matches if the request method matches the specified value. Eg. "GET" or "POST".
m_code => $digit
m_code => $status_code
Matches if the response status code matches. If a single digit is specified; matches for all response status codes beginning with that
digit.
m_proxy => $url
Matches if the request is to be sent to the given Proxy server.
m_media_type => "*/*"
m_media_type => "text/*"
m_media_type => "html"
m_media_type => "xhtml"
m_media_type => "text/html"
Matches if the response media type matches.
With a value of "html" matches if $response->content_is_html returns TRUE. With a value of "xhtml" matches if
$response->content_is_xhtml returns TRUE.
m_uri__$method => undef
Matches if the URI object provides the method.
m_uri__$method => $string
Matches if the URI's $method method returns the given value.
m_header__$field => $string
Matches if either the request or the response have a header $field with the given value.
m_response_attr__$key => undef
m_response_attr__$key => $string
Matches if the response object has that key, or the entry has the given value.
